How many miles per gallon does a Ford F-350 get?
In short, the Ford F-350's fuel economy varies widely by engine and configuration. Diesel versions typically offer better highway efficiency than gasoline models, but the exact mpg depends on drivetrain, cab/bed setup, and whether you’re towing or carrying a heavy payload.
For context, EPA estimates show a broad range: diesel models usually land in the upper teens to low-20s for combined mpg, especially on highway driving, while gasoline engines tend to fall in the low-to-mid-teens for combined mpg. Real-world numbers can be significantly lower when towing or under heavy load. To get the precise figure for your exact build, check EPA ratings for your configuration on fueleconomy.gov or Ford’s official spec sheets.
Fuel economy by engine type
The F-350 is offered with diesel and gasoline powertrains, and each behaves differently under load. The following ranges reflect typical EPA estimates for common configurations and illustrate how drivetrain and body choices influence efficiency.
Diesel: 6.7L Power Stroke
Diesel F-350s tend to deliver stronger highway efficiency and higher torque for towing, with EPA estimates placing combined mpg in the upper teens to low 20s depending on configuration.
- 2WD, Crew Cab, Long Bed: combined around 18–20 mpg; highway about 21–23 mpg; city around 15–17 mpg.
- 4x4, Crew Cab, Long Bed: combined around 17–19 mpg; highway about 19–22 mpg; city around 14–16 mpg.
- 2WD, Regular Cab, Long Bed: combined around 17–19 mpg; highway about 22–23 mpg; city around 15–16 mpg.
These numbers illustrate the impact of drivetrain and body style on efficiency even within the same engine family.
Gasoline engines
Gasoline options generally deliver lower mpg than the diesel when towing or hauling, with typical combined figures in the low teens to mid-teens depending on setup. Highway numbers can reach into the high teens or low 20s in lighter configurations.
- 7.3L Gas V8: combined roughly 14–18 mpg; highway around 17–21 mpg; city around 11–15 mpg.
- 6.2L Gas V8: combined roughly 12–15 mpg; highway around 15–18 mpg; city around 9–12 mpg.
Gas models reflect the trade-off between power, weight, and payload requirements in daily driving and heavy-duty use.
How configuration affects mpg
Beyond engine choice, the exact configuration of the F-350 matters. Drivetrain (2WD vs 4WD), cab style (Regular, Super Cab, Crew Cab), bed length, and whether the truck uses Single Rear Wheel (SRW) or Dual Rear Wheel (DRW) all influence fuel economy. Towing and payload demands also have a sizable impact on mpg.
- 4x4 drivetrains typically lower MPG by a few miles per gallon compared to 2WD due to weight and drivetrain losses.
- Dual-rear-wheel (DRW) configurations generally deliver lower mpg than single-rear-wheel (SRW) setups because of extra weight and rolling resistance.
- Heavy towing or payload reduces mpg significantly, especially in lower gears and on steep grades.
Understanding these factors helps set realistic expectations for real-world fuel economy rather than relying on a single figure.
Where to find exact numbers
For precise EPA-estimated fuel economy for your exact Ford F-350 configuration, use fueleconomy.gov and Ford’s official spec sheets. Enter model year, trim, cab style, bed length, drivetrain, and whether you plan to tow. These sources provide the official city, highway, and combined ratings for your build.
Summary
The Ford F-350’s mpg varies widely by engine and configuration. Diesel variants generally offer better highway efficiency and similar or better combined numbers than gasoline versions, but towing and payload demand can significantly reduce mpg across all setups. For the most accurate figure, consult EPA estimates specific to your exact configuration.
What is the gas mileage on a Ford F-350?
An F-350 with a gas engine typically gets between 10 and 20 MPG, with highway driving averaging higher, while city driving is on the lower end. For example, highway MPG can range from 17 to 20, while city and stop-and-go driving can drop the average to 12 to 15 MPG. Factors like the specific engine (6.8L vs. 7.3L), rear axle ratio, driving habits, and load all significantly impact the actual fuel economy.
Factors affecting gas mileage
- Driving conditions: Highway driving generally yields better MPG (17-20), while city and stop-and-go traffic will lower the average (12-15).
- Engine and transmission: Newer 7.3L gas engines tend to get better MPG than older 6.2L engines. The 10-speed transmission can also affect mileage depending on its shifting patterns.
- Rear axle ratio: A higher axle ratio (like 4.30) can lower MPG compared to a lower ratio (like 3.73) because the engine has to work harder at higher speeds.
- Driving style: Aggressive acceleration and high speeds will reduce fuel economy.
- Load: Carrying a load, whether it's a trailer or a heavy payload, will decrease MPG.
- Towing: Towing a heavy load can drop MPG significantly. For example, a large camper may bring average mileage down to 10-12 MPG on a cross-country trip.
Which V8 truck has the best mpg?
The V8 truck with the best MPG is the 2024 Chevrolet Silverado 1500, which achieves an EPA-estimated 16 city/22 highway MPG with its 5.3-liter V8 engine. Other V8 trucks like the Ram 1500 also have impressive figures due to technology like cylinder deactivation, but the Silverado is a strong contender for efficiency in its class.
- 2024 Chevrolet Silverado 1500: Achieves up to 16 city/22 highway MPG with the 5.3-liter V8 engine, according to Top Speed and Modern Chevrolet of Burlington.
- Other V8 trucks:
- The Ram 1500 uses cylinder deactivation and a mild-hybrid system to achieve a combined 12-22 MPG, notes RealTruck.
- Older models with advanced V8 engines and cylinder-deactivation technology can also achieve high MPG, such as the 2012 Audi A8 which got 28 highway MPG.
- Important consideration: While these figures are for gas-powered V8 trucks, diesel and hybrid trucks can achieve even better MPG, such as the 2025 Chevrolet Silverado 1500 Diesel which can get up to 33 highway MPG, says Mathews Ford.
What is the gas mileage on a 6.6 L 8 cylinder turbo diesel engine?
A 6.6L V8 turbo diesel engine typically gets 15-18 MPG combined, but can vary based on driving conditions and vehicle model. Highway driving may see results closer to 17-21 MPG, while city driving is generally lower. Towing a heavy load will significantly decrease fuel economy, potentially dropping it to around 10 MPG or less.

Estimated MPG by driving condition
- Combined: 15-18 MPG
- Highway: 17-21 MPG
- City: 13-18 MPG
- Towing: As low as 10 MPG with heavy loads
Factors that influence MPG
- Towing and hauling: Adding significant weight will reduce fuel economy.
- Driving habits: Aggressive acceleration and braking, or higher speeds, can lower MPG.
- Vehicle model: The specific truck model (e.g., Chevy Silverado, GMC Sierra) and its configuration (e.g., cab size, bed length) can affect efficiency.
- Terrain and conditions: Hilly roads or stop-and-go traffic will decrease MPG compared to flat, steady highway cruising.
What is better, gas or diesel Ford F-350?
Why Choose a Diesel Truck? Torque and Towing – Diesel trucks generate more torque than gas-powered versions, allowing them to tow heavier loads with ease. This is why they are well-respected work trucks and transport vehicles. Fuel Economy – Diesel engines tend to be more efficient when compared to gas engines.
